SPECIFICATION forming part of Letters Patent No. 620,785, dated March 7,1899. Application filed December 24, 1898. 1 $eria1No. 700,Z40. (Nomodel.)

{b all whom it Jncty concern-.-

Be it known that I, REINHOLD KLATT, of Strong City, in the county ofChase and State of Kansas, have invented a new and Improved \Vrench, ofwhich the following is a full, clear,

and exact description.

The purpose of this invention is to provide a wrench with adjustablejaws which may be set to the nut by a mere'movement of the han- IO dleof the wrench as contradistinguished from operating the jaws through themedium of a screw or like element.

This specification is the disclosure of one form of my invention, whilethe claims del 5 fine the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of referenceindicatecorresponding parts in all the Views.

Figure 1 is a side elevation of the wrench. Fig. 2 is a front viewthereof with parts broken away. Fig. 3 is a fragmentary side elevationthereof with parts broken away to illustrate the operation of thewrench. Fig. 4 is a detail section on the line 4 4 of Fig. 1. Fig. 5 isa similar view on the line 5 5 of Fig. 1, and Fig. Gis a detailperspective View of the link for driving the adj usting-jaw.

The wrench is provided with a handle 6,

having a slot 7, in which is movable abutton 8, such button beingattached to a sliding block 9, mounted in the handle and connected inturn with a rod 10, which carries an expansive spiral spring 11,pressing against a 3 5 double stop-pawl 12. This pawl is pushed upwardlyby the spring 11 (see Fig. 1) and slides in the longitudinally-extendingslot 1-1L of the handle 6, which also carries the rod 10 and spring 11.

4o Mounted to swing on the end of the handle 6, adjacent to the pawl 12,is the main jaw 15 of the wrench, which has an extension 16, forming thejaw proper,and which has a guideway 17, in which is mounted to slide theadjusting-jaw 18 of the wrench. This jaw 18 has an extension 19, movabletoward and from the extension 16 and forming the adjustingjaw proper.Formed on the jaw 15 and concentric to the pivot 20 thereof aresegmental 5o ratchets 21, which act, respectively, with the arms of thedouble pawl 12, whereby to hold the jaw 15 in'the desired position. Thesliding or adjusting jaw 18 is connected with the handle 6 by means of alink 22, and the sliding movement of the jaw 18 on the jaw 15 is limitedby a pin 23, which is fastened in the jaw 15 and extends across betweenthe cheekpieces that form the slideway 17 of the said jaw 15.

WVhen the wrench has its parts in the po- I sition shown in Fig. 1, thejaw 18 will be pushed by the links 22 as close to the jaw 15 as it ispossible for the first-named jaw to move, and consequently the wrenchwill be adjusted for the smallest-sized nuts. When the wrench is in theposition shown by the dotted lines in Fig. 3, the jaws are opened to agreater capacity. Now to adjust the jaws to a nut the wrench in theposition shown in Fig. 3 is placed on the nut and the handle turnedtoward the left, which causes the link 22 to throw the jaw 18 toward thejaw 15, and consequently to close the two jaws on the nut. By means ofthe spring-pressed pawl 12 bearing against the ratchets 21 the jaws willbe held in the desired adjustment, and to release the jaws the pawl maybe drawn back by the button 8.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a wrench,the combination of a handle,

a jaw pivotally mounted thereon and having a ratchet, a pawl sliding onthe handle and engaging the ratchet, a jaw mounted to slide on thefirst-named jaw, and a link connecting the second-named jaw with thehandle.

2. In a wrench,the combination of ahandle,

a main jaw mounted to swing thereon, an adj Listing-jaw mounted to moveon the main jaw, 0 and a link connecting the said adjusting-jaw with thehandle.

3. The combination of a handle having a longitudinally-extending slot, apawl moving in the slot, a rod in connection with the pawl, means formoving the rod, such means being carried to slide on the handle, aspring pressing the pawl, a main jaw pivoted on the handle and having aratchet engaged by the pawl, the main jaw also having oppositely-located10o cheek-pieces forming a slideway, an adjustway, means forsupportingthe jaws, on which ing-jaw mounted to move between said cheekmeans themain jaw is pivoted, and a link 10 pieces in the slideway, and a linkpivotally pivotally connected to said means and to the connecting thesaid handle with the adjustadj Listing-jaw.
